Drivers of Phenotypic Variation Along a Late Pleistocene Range Expansion Route

Journal of Biogeography, EarlyView.
ABSTRACT Aim Understanding how interindividual variation within populations drives the evolution of biodiversity patterns is a major challenge in ecology and evolutionary biology. By reshuffling species distribution in space and time, Pleistocene climatic oscillations shaped the structure of biodiversity.

Spatial distribution patterns and formation of global spermatophytes

Journal of Integrative Plant Biology, EarlyView.
Summary: The global Spermatophyte Spatial Evolutionary System defines 18 distribution types and six supertypes across three floristic elements, primarily formed between the Eocene and Miocene and shaped by climate, long‐distance dispersal, and tectonic movement, revealing that similar distribution patterns of spermatophytes were driven by comparable ...

Fluid or Melt? Distinguishing Syn‐Deformational Interaction Pathways

Journal of Metamorphic Geology, EarlyView.
ABSTRACT Understanding whether deformation occurred in the presence of aqueous fluid or silicate melt is crucial for interpreting ductile shear zones, impacting their thermal and geochemical evolution, and having rheological consequences. To identify the syn‐deformational fluid type, we investigate contrasting shear zones active during the Alice ...

Osteohistology of the unusually fast‐growing theropod dinosaur Ceratosaurus

Journal of Anatomy, EarlyView.
We report the histology of multiple elements attributed to four individuals of Ceratosaurus. We find that the histology and growth models corroborate previous reports of rapid tissue growth in the genus. Abstract Ceratosaurus is a large‐bodied non‐avian theropod dinosaur known from the Upper Jurassic Morrison Formation of North America and is ...

Intraskeletal histovariability and skeletochronology in an ornithopod dinosaur from the Maestrazgo Basin (Teruel, Spain)

Journal of Anatomy, EarlyView.
Abstract Ornithopods are an extinct group of dinosaurs that were particularly abundant and diverse in the Cretaceous of the Iberian Peninsula, and whose abundance in the Maestrazgo Basin has allowed numerous taxa to be identified over the last decade. Many of these fossil remains are still taxonomically indeterminate and require a more detailed study ...
